To return the movable apron-to its initial position there is provided a sprocket wheel 50 'loosely mounted upon the axle and adapted to slide lengthwise thereon and connected with asprocket wheel 51, secured to' shaft 9, by means of a chain 52;l the sprocket wheel 50 being provided with clutch teeth'53 on its hubfportion adapted to en age'witha toothed clutch member 54 secure 'to the' axle, wheny the socket wheel is moved along the axle in one rection, and to `be disengaged therefromwhen moved in an op ositefdirection. To move said s rocket whee alon the axle 36,` the 'ribibein'g operative in a manner to).

there is vprovi ed a bell crank ever 55, v

mounted m a vertically arranged bearing .56, secured to a cross member 57,'of the body frame, said bell 'crankhaving a rearwardly lextending arm l58, to which is secured a fork 5 9 that embraces the hub of the s 4rocket Wheel in a Wellfknown way and whic isoperative to control the movement thereof, and

60 represents' a laterally extending arm forming a part of said bell crank.

The mechanism whereby the operator fis enabled to control the movements of the various operative parts of the 'machine comprises a rock-shaft 61 arranged in front of and parallel with the aX-le, and mounted in suitablebearings secured to the body frame members, and secured to said rock-shaft intermediate its ends, is a sector 62, which sec- .'tor is llexibly connected with jan arm 63 of a handv lever 64 pivotally mounted on the foot board at the front of the machine and having a common frm of sliding hand controlled detent 65 mounted thereon 'and adaptedto eni gage with either of two notches 66 formed in a sector 67 secured to the foot board adi have a limited independent movement,

which movementis controlled by a pin 681` the lever, and a link 69 havingits rear end pivotallycon'nected with one arm of said leveriand its forward end slidably mounted in a'bracket 7 0 secured to the body frame;

:engaging with a suitable stop shoulder on the lhub pf and havingr acoiled spring 71 surrounding 'the link and operative against theu forward Vside of the bracket-in a mannerto 'draw the link in a forward direction, and through its connection with lever '68 yieldingly oppose a movement of vthe rock-shaft when said hand levcr,.is moved in one direction, and' to cause said'lrock-shaft to turn in an opposite direcf,

tion when the hand lever is released. The other arm of lever 68 is connected, by means of a link 72, with the cam lever 26 forming part of the clutch shipping mechanism connected with the main sprocket wheel 21 ;v the arran ement of the arms and links being such iliat when the hand lever is in the position shown by full lines in Fig. 8 the shaft 61 has been/rocked in its bearings to its full limit in a forward direction, caused partly by the force of the spring 71 acting through its link connection with lever 68, and other means to be .described later. When in this position the main sprocket wheel is unclutched from the adjacent dog plate and the clutch shipping parts are in the position shown in .Fi 5, and the pin 681, moving around with tie rock-shaft, is in the position shown in Fig. 3 relative to the stop shoulder on lever 68.

Secured to opposite ends ofthe rock-shaft,`

outside of its supporting bearings, are arms 73 and 74, and said arms are pivotally connected with the side levers 16 of the end gate mechanism by means of vertically arranged links 75, and arm 74 is connected withy the worm controlling cam 41 by means of a link 76, having a slot at its forward end that receives a stud 77 secured to the arm 74, and a spring 78 is mounted in the slot in a mannerto yieldingly control the eii'ective operative length of the link.

With the parts inrtheir various ositions as shown in Fig. 8, the arms 7 8 and) 7 4 are depressed by means of the weight of the end gate acting through the pivoted side levers has been rotated rearward and the arms 73v and 74, through the connecting links, have raised the end gate; the pin 681 is in contact with the stop shoulder on lever 68, and the link connection between arm 74 and the cam lever 41 is in position to cause the latter to swing in a manner to allow the worm to engage withthe worm wheel. When the hand lever is moved to the position shown by full lines in Fig. 2, the spring 71 has been compressed by the movement of. lever 68 and the cam` lever 26 has thereby beenswimg-ior-v ward in la manner permitting spring. 28 to move .the rod 25 and allow the clutch members to engage with each'otheryand in this position of the parts the Worm has engaged with the worm wheel unless prevented by means of the teeth contacting, and if such be the case the spring 78 will yield suilicient to allow o f the eilective length of the link 76 being shortened and it will cause the .parts'to engage as soon as they are in proper position.

7 9 represents a lever pivoted coaxially with the hand lever, having an inclined sur'- face at its upper end adapted to engage with the sliding detent 65 ina manner to disengage it from the sector when moved in one direction, and its lower end pivotally connected with a sliding bar 80, supported at its rear end by a bracket 8 1 and having a depending arm 82 secured thereto, which arm .is adapted to contact with the apron in .a manner to cause the bar to slide forward and rock hand lever to swing forward to the position shown by dotted lines in Fi 2 bymeans-of the force of spring 7 1, acting t ough the rockshaft and its associated parts, and a spring 83 surrounds the bar at its rear end and is operative against the bracket 81 in a manner to return tlie bar to its original osition as soon as the resistance is remove The cylinder operating and a ronl advancing means are now unclutched rom their respective driving means, and the manually controlled mechanism for returning the apron to its initial position for receiving a load is operative in the following manner: 84 represents afoot lever pivotally mounted-upon the foot board and having its lower arm vpivotally connected with a sliding bar 85 the rear end of saidibar being pivotally connected with the laterally projecting arm 60 of the bell crank lever 55, and it is also connected with lever-44 by means of a link 86.

` The hand lever 64 is secured to one end of a rock-shaft 87, supported in suitable bearings, a'nd at the opposite end the shaft is -provided with a turned -up portion 88 adjacent said foot lever that is adapted to contact with a laterally projecting lip 89, forming part of said foot lever, in a manner to limit tive to ay toothed holding rack 93,- secured to the upper edge of the'bodyandembracing said hand lever.' I v When fit is desired 1 to adjust the :change speedgeargforming .partA Vof the means for4 movingjthe' apronr'earwardly Atoward the distributing cylinder, the operator-depresses the foot lever'84until the lip portion 89 contacts with the turned up portion 88 of rockshaft 87, which movement ofthe leveris sufficient to cause link 86 to lrock the lever 44 about its axisin amanner to cause the spiral iso rib upon its hub portion to coperate'with the notch in the part 49 and'slide the shaft 35 and thereby cause `gear 34 to be disengaged from the pinion, when the latter may be moved in either direction along its supporting shaft by means of hand lever. 90, and

when the pressure is removed from the foot lever a -spring 94 surrounding a stud 95, secured to one of the cross bars 96 of the body frame, the spring operating between the .outer end of the stud and a clip 97 secured to -the bar 85 in a manner to return the foot, le-

ver to its initial position.

When the apron has reached its limit of rearward movement the mechanism for moving it in that direction, and also the means for driving the distributing cylinder, are automatically disconnected, as befcre dey ver-55 in a manner to cause the sprocket wheel 50 'to engagewitli the clutch member 54, and thereby move the apron in a forward direction. When thea ron has nearly reached its limit of forwar movement it contacts with a bracket 9.8 secured to the bar 85 and forcibly moves the bar forward and elevates the foot lever and disconnects the clutch members.
